-Toward the normal
-Away from normal
-Doesn’t bend
2. Which way does light bend when traveling from glass to air?
-Toward the normal
-Away from normal
-Doesn’t bend
3.Of your three mystery materials, in which will light travel the fastest? Why?
Answer:
1: toward the normal
2:away from normal
3: red because the index of refraction ( the ratio of the speed of light in a vacuum to the speed of light in a material) is increased for the slower moving waves
The frequency and wavelength of the sound wave with the given time period and speed are 500Hz and 0.688m respectively.
Period is simply the time taken for a complete cycle of vibration to pass a given point. Frequency is expressed as;
f = 1/T
Where f is frequency and T is period of time.
Given that;
f = 1/0.002s
f = 500s⁻¹
f = 500Hz
Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.
From the wavelength, frequency and speed relation,
λ = s ÷ f
Where λ is wavelength, s is speed and f is frequency.
Given that;
λ = s ÷ f
λ = 344m/s ÷ 500s⁻¹
λ = 0.688m
Therefore, the frequency and wavelength of the sound wave with the given time period and speed are 500Hz and 0.688m respectively.

Answer:
Given
Time (T) = 0.002 sec
Velocity(V) = 344 m/s
Frequency (f) = ?
Wavelength (w) = ?
Explanation:
We know that
Frequency (f) = 1/ t
= 1/ 0.002
= 500 hertz
Now
wavelength = V/f
= 344/500
= 0.688 m
Answer
Hi,
An increase in amplitude from 3m to 6 m increases the energy it transports. The frequency of the wave is not affected
Explanation
Amplitude is the height of a wave where as frequency is the number of waves that pass by each second. A wave with bigger amplitude has more energy than a wave with smaller amplitude. A point where more waves pass contains more energy that is transferred every second. The change in the amplitude of a wave does not change its frequency. However, frequency is inversely related to the wavelength of a wave.

A radiologist performs multiple tests including radiography (X-rays), MRI, CT scans, and ultrasounds to diagnose and treat various diseases and injuries.
A radiologist is a medical doctor specialized in diagnosing and treating diseases and injuries using medical imaging procedures. One of the key tests performed by a radiologist is a radiography, also known as X-ray. In this test, a small amount of radiation is used to produce images of the inside of the body. They also perform other tests such as Magnetic Resonance Imaging (MRI), Computed Tomography (CT) scans, and ultrasounds, depending on the nature of the patient's condition.
